Sleeve box with two covers dieline
An open-ended glued sleeve between two shallow tray covers, one telescoping over each end. Goods stand on the base cover, the sleeve slides down over them and the top cover closes it; the doubled walls at each end stack well. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
